this came in usefull for me so il thought i would ad it here

Code:

<?php
function shortenurl($url){
    $length = strlen($url);
    if($length > 45){
        $length = $length - 30;
        $first = substr($url, 0, -$length);
        $last = substr($url, -15);
        $newurl = $first."[ ... ]".$last;
        return $newurl;
    }else{
        return $url;
    }
}

$longurl = "http://www.google.com/search?hl=en&client=firefox-a&channel=s&rls=org.mozilla%3Aen-US%3Aofficial&hs=BCR&q=metacafe&btnG=Search";
$shorturl = shortenurl($longurl);
echo"<a href=\"$longurl\">$shorturl</a>";
?>

$longurl is the long url that you want shortened.
$shorturl is calling the function to shorten the url down to 45 characters.

// [img]resize.php?path=imagepath[/img] where path is a relative path such as subdirectory/image.jpg 
$thumbsize = 200; 
$imagesource = $_GET['path']; 
$filetype = substr($imagesource,strlen($imagesource)-4,4); 
$filetype = strtolower($filetype); 
if($filetype == ".gif") $image = @imagecreatefromgif($imagesource); 
if($filetype == ".jpg") $image = @imagecreatefromjpeg($imagesource);

imagecopyresized($thumb, $image, 0, 0, 0, 0, $thumbwidth, $thumbheight, $imagewidth, $imageheight); 
imagejpeg($thumb); 
imagedestroy($image); 
imagedestroy($thumb);
